Immunological tolerance to many self epitopes may be unnecessary. 1990

The demonstration of the existence of antigenic mimicry suggests that immunological tolerance to self antigens may be an insufficient basis for distinguishing self from non-self. However, some data suggest that even in the absence of tolerance most self epitopes would not immunize the host and that tolerance to all self epitopes may, therefore, not be necessary for the prevention of autoimmune disease.

UI	MeSH Term	Description	Entries
D007108	Immune Tolerance	The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.	Immunosuppression (Physiology),Immunosuppressions (Physiology),Tolerance, Immune
D006085	Graft Survival	The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host.	Graft Survivals,Survival, Graft,Survivals, Graft
D006243	Harderian Gland	A sebaceous gland that, in some animals, acts as an accessory to the lacrimal gland. The harderian gland excretes fluid that facilitates movement of the third eyelid.	Gland, Harderian
D006649	Histocompatibility Antigens	A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000951	Antigens, Neoplasm	Proteins, glycoprotein, or lipoprotein moieties on surfaces of tumor cells that are usually identified by monoclonal antibodies. Many of these are of either embryonic or viral origin.	Neoplasm Antigens,Tumor Antigen,Tumor Antigens,Antigen, Tumor,Antigens, Tumor

D013950	Thymus Gland	A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
